"' HULLER.

Application liled March 20, 1925. Serial No. 16,875.

This invention relates to a separator and huller and particularly to aseparator adapted for the hulling of beans. It has for one object toprovide a machine in which stones, dirt and foreign matter generallywill be automatically removed from the material before it reaches theseparating zone. Thus the impurities are separated out from the materialwhich passes through the ma chine, and the machine itself is freed fromforeign matter which might damage it or cause clogging or unsatisfactoryoperation of the machine itself. Another object is to provide a machinein which the foreign matter separated out from the material as it passestoward the final separating zone is thrown out of the machine entirely.Other objects will appear from time to time throughout the specificationand claims.

My invention is illustrated more or less in the accompanying drawings.wherein:

Figure 1 is a vertical longitudinal section of a portion of the machineshowing the stone picker mechanism and associated parts.

Figure 2 is a side elevation of tion of the machine; I

Figure 3 is a side elevation similar to Figure 2 showing the reverseside of the machine and particularly showingthe driving connection.

Like parts are indicated by like charac ters throughout.

A represents generally the housing which encloses the mechanism. B isthe enclosing and supporting housing within which it conveyor preferablyof the belt type is mounted and which conveys the material to theseparating zone. C is the belt conveyor provided with slats or cleats C.It revolves at one end about a pulley C which is carried-upon a shaft CC is a floor beneath the belt. C is an extended covering member whichforms in effect an extension of the floor C and is curved about theshaft C It serves among other purposes to prevent material that por-vwhich is brought in on the conveyor from falling down and escaping thestone picker drum.

D is a shaking pan. Its lower end is slidably mounted-on the plate D andadjacent its upper end it is engaged .by one or more 7 rocker arms Dcarried on the rock shaft belt pulley F".

separator frame. D is a'lever arm which is attached to the rock shaft Dand connected at its 'free end to a pitman D which is carried upon acrank pin secured in the pulley D on a shaft D The pulleyan'd shaft aredriven, in a manner which. will be described below.

E is a concave provided with removable teeth E and in co-operation withit is the cylinder F mounted on a shaft F which carries at its outer enda driving pulley F adapted to be driven-by the. belt F from any suitablepower source. Mounted in the cylinder F are removable teeth F. Thedetails of the concave and. its associated parts will not be describedfurther as they form no part of the present invention. F is anadditional driving pulley mounted on the shaft F and adjacent to. thepulley F At the opposite end of the shaft is a third Mounted above theshaker panon a shaft G' is a stone picker cylinder G provided with teethG which may be removable and are preferably rearwardly bent as shown.The shaft G carries at its outer end a belt pulley G which i is incontact with and driven by a belt N.

H is a beater carried on-a shaft H It is mounted behind and slightlyabove the stone picker cylinder and nerally above the cylinder F. Theshaft 1 carries at one end a belt pulley H Between the pulley H and thepulley D on the shaft 1)? is a crossed belt H On the shaft H? at theopposite end from that which carries the pulley H is a second beltpulleyH.

I is a belt tightening pulley carried in an arm I which is pivoted at Iand provided with a handle extension I. positioned adjacent to aquadrant .1 provided with a locking nut I by means of which it may belocked in fixed position with relation to the quadrant.

Between the carrier and the stone picker cylinder and slightly below thecarrier is a shield J. This shield runs transversely across the machinethroughout substantially the width of the carrier. It may be flexibleand under certain circumstances the members C of the carrierwill strikeit and deflect it slightly downward, and it is to ermit this that it isgenerally preferably exible. It is removably fastened to a. transversemember J K-is a deflector plate The arm is situated in the upper part ofthe machine. It is preferably metallic.

L is a stone receiving compartment having an open side L in which ishung a swinging curtain L preferable flexible. In the top of thecompartment L is hinged a cover L. The compartment L has in its bottom,raised slat members L. M is a swinging cover for aportion of the maincasing which may be raised for inspectlon purposes and to permitentrance into the machine for repairs and other pur oses.

N is a belt which is mounted a out the pulleys F H, G and I. O is asprocket on the carrier shaft O is a sprocket pinion on the shaftD andis a chain about the two 3 rockets by means of which the carrier 'sha tis driven from the shaft D". O is'a chain tightening sprocket pinionadjustably mounted at O.

P is a flexible downwardly depending curtain mounted at the mouth of themachine and depending downward toward the carrier belt and into thenormally entering path of the material which is carried there by. Whenmaterial is being fed to the machine this material is frequentlydeflected rearwardly. During the operation of the.

machine any material which may be driven toward the feeding opening ofthe machine will strike the curtain and will be deflected by itdownwardly and be prevented from flying out of the machine.

Although I have shown an operative device, still it will be obvious thatmany changes might be made in size, shape and arrangement of partswithout departing materially from the spirit of my invention; andv Iwish, therefore, that my showing be taken as in a sense diagrammatic.Particularly where in the specification and claims I have used the wordgrain I mean grains of any sort. It might be wheat, oats, beans or anymaterial which in growth is associated with pods, chaff, stalks andother matter from which it must be separated.

The use and operation of my invention are as follows:

When the machine is to be used, the mechanism is set in operation andmaterial is placed 11 on the feeder and by it carried toward t e feedopening. Material passes off of the feeder carrier and against the stonepicker cylinder. The teeth of this cylinder contact stones. lumps ofdirt and other foreign matter and drive them upwards against thedeflecting plate K and from this plate they are deflected against theupper curtain which hangs in the door way of the chamber L. the heavymaterial swings the curtain and passes into the chamber, and lightermaterial fails to swing the curtain and drops downward again into themachine and is carried forward toward the hulling and separating zone.

Some material will be deflected outward toward the feeding opening andwould be driven out of the machine. To prevent this the curtain P ishung in the opening and material driven toward the feeding openingstrikes the curtain and is deflected by it downward and drops into thestream of material coming into the machine and is prevented from flyingfrom the machine. Thus means are provided both for separating foreignmatter from the material to be liullcd and separated. and for preventingthe accidental discharge of material from the machine by reason of theaction of the stone picker.

All remaining material is, of course, caughtby the stone picker cylinderand carried upward and over, and thrown in the direction of the beater.The heater strikes this material and forces it downward again toward theconcave and the threshing cylinder which co-operates with it. The heateralso sets up an air current which further blows and diverts materialdownward toward the concaves and the threshing zone.

The driving mechanism operates as follows:

The main cylinder shaft F is driven from any suitable power source. Fromthis shaft the beater shaft, and the stone picker shaft are driven. Fromthe beater shaft H the shaft D is driven and from the shaft D thecarrier shaft C and the shaker pan D are driven.
